I’m changing my stock fan for two 10” fans. My question is the OEM fan has 3 wires; Black and yellow on the ends and green yellow in the middle and the new fans have 2 wires. they are push/pull fans. What OEM wires do I hook up to the fans? The OEM fan has yellow as positive and black is negative but the green and yellow has nothing. And my Hanes book is little help on this one.

The stock fan is two speed. One wire for high, one for low. The black is the ground.
That’s what I thought but how would you wire the 2 fans up? Like option 1 or option 2?
Also does anyone know which one is low and which one is high?
Yellow is the high.
Why are you changing the fan ? Are you boosted ?
Here is a PIC of the mockup. And yes I’m going to be boosted. I have a thread in forced induction “new start to an old project”
So ZX2 Spleeper would that sound like option 2?
And Dougiestyl way don’t you like option 2?
Just curious, why are the fans in front of the radiator?
Granted I don't know much about fans in general, aren't they supposed to be behind it so that they cool the engine bay?
Side question- Are fans really that neccesary? Wont the coolant do its job?
These are universal fans. They can push or pull depending on how we want to mount them. Here is PIC way they need to be in front.
And for the need of the fan, they are a must. The more air you can put through the radiator the better you can keep the system cool.

OH! so yours are pushing then I assume?
And again, how necessary are fans? Can we do w/o?
I edited the other reply and answered that
I see now. So are the stock fans "pull"?
So its not really blowing on the motor but actually pulling air through the radiator to cool it?
That is correct
I see now. Well I repped you for all your help! Thanks for everything. Sorry to derail... lol
Put the wires together, and run them to the hot fan connection[s]. Use the ground as is
Option 2 is what I would use.
